Described shifting method bottom blowdown water refers to installation sewage disposal facility at the bottom of culturing pool from the system of overflowing, its sewage disposal facility is included at the bottom of the pond of culturing pool has certain gradient, then the lowest part at the bottom of the pool is provided with sewage draining exit, be provided with at sewage draining exit place and prevent escaping net, pond main body is communicated with blowdown pipelines by the sewage draining exit at the bottom of pond, then the side of culturing pool is provided with solid-liquid separation tank, the water outlet end of blow-off pipe is communicated with top with in the middle part of solid-liquid separation tank, the solid content blow-off pipe of band stop valve is provided with bottom solid-liquid separation tank, solid-liquid separation tank top is provided with sewage supernatant drainpipe, sewage supernatant drainpipe is communicated with artificial swamp by pipeline.It is high that drainage can keep upper strata dissolved oxygen here, discharges bottom culture sediments and sewage, reach dredging effect.For fish create good growing environment, peasant household continues healthy aquaculture for realizing, and guarantees that quality safety lays the first stone.Shifting method bottom blowdown water can adopt publication number to be the foul drainage system at bottom of pond for culture recorded in CN102696534A from the system of overflowing.
1) be equipped with oxygen increasing equipment in cage culture district and carry out compound oxygenation, promote levels and surface water flowing,
Increase water body dissolved oxygen; According to the concentration of breeding water body dissolved oxygen, pH value and intensity of illumination adjustment Feeding time and feeding rate; Oxygen increasing equipment comprises micro-pore oxygenation machine (or surge machine), impeller automatic aerator and water-mill oxygen increasing machine, and three kinds of machines are independent or in parallel, and common promotion levels and surface water flowing, increase water body dissolved oxygen.
3) use floating bed planting aquatic plants, carry out the breeding of pond culture wetland outside net cage and combine, realize fish dish
Symbiosis, biological cleaning water quality.Use biologic float bed planting aquatic plants, Absorbable rod water nutrition, aquifer cultivation filter-feeding and ominivore-fish, reach water quality standard for fishery recycling.
4) science is breeded fish.First according to the concentration of breeding water body dissolved oxygen, pH value, intensity of illumination and fish
Situation of ingesting adjustment Feeding time, the concentration of dissolved oxygen, pH value, intensity of illumination all carry out tracking measurement at any time by instrument, at the concentration > 5mg/L of dissolved oxygen, or pH value is thrown something and fed when being 7.5 ~ 8.5, select the place bait throwing in that dissolved oxygen is high, bait throwing in frequency is 2-4 time, and feeding rate is 2-5%.Only when dissolved oxygen abundance, the organic substance ability complete decomposition in water body, material recycle could be accelerated, and noxious material such as molecules of ammonia, hydrogen sulphide, aldehyde ketone (anaerobic fermentation of organisms product) etc. also can be converted into nontoxic or low toxicity material.So dissolved oxygen is the most important condition of fish growth and water circulation.
Its pH value cultivating the water adopted is 7.5-8.5, molecules of ammonia≤0.02mg/l, the concentration of dissolved oxygen
Be greater than 5mg/l.Carry out cage culture, it need pass through sterilization when first time pours into new water, just can stocked carp after 5-7 days lack of toxicity.It is 82:18 that master should be made in the fingerling of putting in a suitable place to breed to breed fish with the quantitative proportion of raising together with fish.According to the concentration of breeding water body dissolved oxygen, pH value and intensity of illumination adjustment Feeding time and feeding rate, its place bait throwing in that dissolved oxygen should be selected high, bait throwing in frequency is 2-4 times/day, and feeding rate is 2-5%.
The water plants of biologic float bed plantation is water harmony dish, oenanthe stolonifera, water lily or three Plants mixed plantings.
Fish are in low temperature season winter or early spring, and November then-March in next year puts fingerling in a suitable place to breed in culturing pool, need carry out disinfection when putting in a suitable place to breed to fingerling, and with 3-5% saline sook 20-30 minute, or the potassium permanganate immersion of 20g/ every cube water is put into after 15-20 minute again.Saline sook is to adopt salt solution to carry out disinfection, principle is for increasing osmotic pressure, make causal organism dehydration and dead, certain disinfecting power is had to bacterial fungus parasite etc., potassium permanganate has the cell membrane of Strong oxdiative performance oxidation causal organism, both sterilization scopes are wide, and not easily form drug resistance.
In this method, topmost technology is exactly that science is breeded fish, and science is breeded fish and referred to and adopt innovation " seven words " scientific culture pattern, is summarised as " water, kind, material, point, mixed, anti-, work ".Wherein:
Water: fish culture water requires that water source is convenient, sufficient, and water quality is pure and fresh pollution-free, meets water quality standard for fishery.Wherein, pH7.5-8.5, molecules of ammonia≤0.02mg/l, in the continuous 24h of dissolved oxygen, whole day, in 24 hours, has the concentration of more than 16 hours dissolved oxygens to be greater than 5mg/l, and whenever all the other must not lower than 3mg/l.Only when guaranteed dissolved oxygen abundance, the organic substance ability complete decomposition in water body, material recycle could be accelerated, and noxious material such as molecules of ammonia, hydrogen sulphide, aldehyde ketone (anaerobic fermentation of organisms product) etc. also can be converted into nontoxic or low toxicity material.So dissolved oxygen is the most important condition of fish growth and water circulation.But, due under the highdensity intensive culture condition in pond, drop into the fish excreta of a large amount of feed generation and residual bait, caused water body organic loading and increase, consume a large amount of dissolved oxygen thus cause water body easy anoxic when bacterium is decomposed.
During cultured fishes, after the desilting of the dry pool, through sterilization, after 5-7 days, new water can be poured into, just can stocked carp after drug toxicity disappears.In fish culture process, can regulate the dissolved oxygen in water body according to the method described above, also can be aided with probiotics carries out water quality adjustment simultaneously.
Kind: putting fish in a suitable place to breed will determine according to local market demand, consumption habit, weather conditions and the technical merit of self, and fingerling requires anosis without wound, physical health.Choose according to above factor and put kind in a suitable place to breed, can put into pond at low temperature season (winter or early spring, November-March), water temperature low fish movement intensity is weak, reduces fish injured, can extend the fish growth time simultaneously.Stocking size should according to listing specification determine, as listing specification be 3 jin, then stocking size be at least 3 liang (yearlingses) and more than, growth cycle is long, and stocking size about 3 liang, growth cycle is short, then suitably improve.Breeding density is determined according to listing specification, plan yield and expection survival rate (aquaculture management level is larger on survival rate impact).As per mu yield 3000 jin, listing specification 3 jin, survival rate 80%, then mu breeding density is 3000 ÷ 3 ÷ 80%=1250 tails.And in the application, require to put in a suitable place to breed early numerous fingerling, listing specification can be reached then.As: predacious fish Silurus meridionalis Chen, on average can reach 1-1.5 kilogram, and carp can reach more than 0.5 kilogram, and grass carp can reach about 1 kilogram.Put early-breeding seedlings kind in a suitable place to breed, predacious fish can be sold then, shortens the culture-cycle, decreases fingerling cost.When putting fingerling in a suitable place to breed, through sterilization, available 3-5% saline sook 20 minutes, or potassium permanganate 20g/ every cube of water, soak 15-20 minute.
Attention: one is numerous fry morning: winter, artificial greenhouse controlled water temperature at 24-26 DEG C to parent population reinforced cultivating, and parent population does sth. in advance about 30-60 days maturations, numerous fry 30-50 days more Zao than tradition;
Two is early put high-quality fingerling: put physique in a suitable place to breed and strengthen, specification is large, high-quality catfish kind that quantity is sufficient, Catch-up growth most thermophilic season, and innovation prime fish kind forms one batch or two batches of marketable fish, changes and forms marketable fish history in 2 years.
Material: comprehensive nutrition of throwing something and feeding, meet the manufactured feed of Studies On Nutritional Requirements of Cultured Fish, if predacious fish is 32-40% by Different growth phases protein requirements, not containing the violated additive such as hormone and antibiotic in feed, can not be putrid and deteriorated.Tradition cultivation is thrown something and fed and is followed timing, fixed point, determine matter, quantitative " four is fixed " principle, and this patent has made following change: one be timing is thrown something and fed innovation is dissolved oxygen according to breeding water body, pH, illumination and fish situation of ingesting change flexibly and adjust Feeding time.Be typically chosen in dissolved oxygen higher, the concentration > 5mg/L(of dissolved oxygen or within 1 hour, open aerator adjustment in advance) or pH7.5 ~ 8.5 time throw something and feed.The pH of water body is too high, pH value > 9, and in breeding water body, ammonia nitrogen toxicity strengthens, thus works the mischief to cultured fishes.Two is fixed point is thrown something and fed innovation for according to wind vector in season, and other physical and chemical factor situation of change of Chi Shui, selects the place bait throwing in that dissolved oxygen is high.As intensive fish pond, fine day generally should select air port place under fishpond afternoon, because of the effect of lower air port place by wind, assemble a large amount of plankton and carry out photosynthesis, its dissolved oxygen is often higher than uptake, and the levels water mixing uniformity is high, be conducive to sufficient dissolved oxygen demand when ensureing fish and higher bait grazing rate.Be 2-4 time according to different seasons and vegetative stage bait throwing in frequency, feeding rate is 2-5% and grasps flexibly according to the active situation of weather condition and fish at that time.Bad weather, the cloudy day is especially overcast and rainy, and dissolved oxygen is low, and fish movement is weak, can reduce throw something and feed number of times and feeding volume, no longer ingests be as the criterion to finish rear a large amount of about about 80% fish.
Point: in net cage, cultivation fry is sieved by different size for kind 7-10 days, big fish swallowing little fish to prevent predacious fish, and the individual difference that the inequality of ingesting brought because fingerling specification is different causes is comparatively large, makes seed size neat, growth rate is consistent, and survival rate improves.Fry is from during spray forming specification fingerling, because seed is in the juvenile fish stage, metabolism is vigorous, and fast growth, can cause individual difference, specification is uneven, predacious fish also can cut one another's throats, and fish loading amount and density increase easily cause anoxic, cause lethality to raise, survival rate of fish fry is less than 20%, and output reduces.Therefore in breeding process, point pond need be carried out to seed and raise, greatly can improve survival rate, reach 90% and more than.Its concrete method for sieving is that spray breeding density is 200,000 tails/mu, and when growing to very little sheet, screening is 100,000 tails/mu, and when growing to 2 cun of specifications, screening is 50,000 tails/mu, when growing to 3 cun of specifications, sieves as 2-3 ten thousand tails/mu.When carrying out adult fish culture, breeding density is 800-1500 tail/mu.
Mixed: for making full use of pond waters space, play the mutual reciprocity and mutual benefit between breed variety, after determining main foster kind, suitably should arrange in pairs or groups and raise together with kind, can arrange in pairs or groups by 82:18.Raise together with kind based on filter-feeding fish, can total fish catches be increased, can also regulating water quality.Raising together with in kind, a small amount of predacious fish (as largemouth bass, mandarin fish etc.) of also can arranging in pairs or groups, utilizing it to control wild fishes quantity, gather in the crops the aquatic products of high-quality simultaneously.
Anti-: diseases prevention is to raising immunity future development (rely mainly on prevention, control combines).Morbidity season is every 15--20 day povidone iodine disinfection; I.e. 1m 3water body 0.45 ~ 0.75ml(every mu water body depth of water, 1 meter of use 300 ~ 500ml), the next day once, be used in conjunction 2 times, can prevent and treat caused bleeding by bacteriums such as vibrios, Aeromonas hydrophila, tardas, the bacteriosis such as gill rot, furuncle sore, Beancurd sheet.Or every cube of water body probiotics 0.2g full pool spilling head such as bacillus, can prevent fish disease; Regularly (every 20-30 days) mix pharmaceutical chemistry to add in feed salt 200g, multidimensional 50-100g, allicin (2g) or the garlic 500g of every 100 kilograms of fishes, and throwing something and feeding every day one time three days is a course for the treatment of, to improve immunity and prevention bacteriosis; Carry out simultaneously anti-to escape, take precautions against natural calamities, antitheft etc.
Work: supporting assembly mechanical oxygenation, water-mill oxygen increasing machine, impeller automatic aerator and micro-pore oxygenation machine (or surge machine), and three with the use of, the globule that water-mill oxygen increasing machine impeller stirs adds the contact area with air, be conducive to the oxygen in dissolved air, the water simultaneously stirred due to eddy current effect can make water body top layer occur exchange up and down, dissolved oxygen distribution comparatively average; The stirring of impeller automatic aerator can break the thermocline of water body, and (water layer changed suddenly for temperature is called thermocline, the diffusion of water body dissolved oxygen can be hindered), make upper and lower water layer convection current more obvious, the water body of upper strata dissolved oxygen abundance can quickly diffuse to water body lower floor, and dissolved oxygen distribution is more average; Micro-pore oxygenation machine, by directly squeezing in water by air, adds the dissolved area of oxygen in water body and air, and upper and lower water layer also can be carried out convection current by the impetus of air, reaches oxygen and is uniformly dissolved; Three with the use of, can keep the good dissolved oxygen condition of water body, every 15 mu of ponds are equipped with 1.5kw water-mill oxygen increasing machine, 1.5kw impeller automatic aerator and 1kw micro-pore oxygenation machine.Two is that regularly to discharge bottom organics content high, and the sewage of easy anoxic, reduces the oxygen consumption factor in water body, and annotate new water in upper strata simultaneously.Three is plant aquatic macrophyte in water, as water harmony dish (bengal dayflower herb), oenanthe stolonifera, water lily etc., utilizes the nutriment in the photosynthesis absorption water body of plant, accelerates water body material recycle, increase the dissolved oxygen of water body, can plant by pond area 1-3% area.Device for feeding fish bait and bait table are installed, reduce labour intensity, be convenient to management.
This method of breeding fish engineered in also comprise reconstruction culturing pool, reconstruction culturing pool refers to and first carries out erection net cage according to the size of culturing pool and the degree of depth of water, the area of general net cage is no more than 2% of pond area, long 1-3 rice can be selected, wide 1-3 rice, high 1-2 rice sets up, and net cage can be installed by isosceles triangle, often arrange net cage spacing more than 10 meters
